Milne Bay Province dive sites

Milne Bay is distinguished by its world-class muck diving combined with healthy coral reefs and WWII wrecks, all in one region. While Kimbe Bay is known for reef diving and seamounts, Milne Bay's black volcanic sand slopes harbour an extraordinary density of rare critters including rhinopias, hairy frogfish, and flamboyant cuttlefish. The bay also has historical significance as the site of Australia's first land victory against Japan in 1942.

Most divers reach Milne Bay via Alotau, the provincial capital, which has regular flights from Port Moresby on Air Niugini. From Alotau, liveaboard dive vessels and shore-based resorts provide access to the dive sites. Several liveaboards operate seasonal itineraries through the bay, while a handful of dive resorts offer shore-based diving with boat transfers to the sites. Advance booking is essential as capacity is limited.

Intermediate certification and strong buoyancy control are recommended. Muck diving involves hovering close to sandy or silty bottoms without disturbing the substrate, which requires precise buoyancy skills. The critters are small and well-camouflaged, so patience and a good eye are essential. An experienced guide is invaluable for spotting the rarest species. Some reef and wreck sites in the bay are suitable for beginners.
